What i am wanting to do is put a larger throttle body on the 3s. The reason is that i am putting on a front mount and am wanting to achieve maximum flow, changing the size of the piping before the i/c won't help the flow, but if i enlarge the piping after the i/c it will flow better. But there is no point in making the piping larger than the throttle body as it will make a bottle neck.
To put on a larger throttle body, will i need to change the inlet manifold at the same time? Is the Group A throttle body larger than the Standard gen 2?
Bear with me as i'm currently unable to walk, so am unable to check sizes on the engine.
So maybe you'd be lucky and bolt the 205 TB to the 185 manifold. Not sure thou.
EDIT: The gasket part numbers are different... 22271-88381 for Gen2, 22271-88480 for the Gen3, but of course, knowing Toyota, that doesn't mean its different
